We found antibiotic-resistant bacteria and traces of a veterinary drug

Consumer Reports magazine: January 2013

Our analysis of pork-chop and ground-pork samples from around the U.S.
found that yersinia enterocolitica, a bacterium that can cause fever,
diarrhea, and abdominal pain, was widespread. Some samples harbored other
potentially harmful bacteria, including salmonella. And there are more
reasons to be concerned about "the other white meat."

Some of the bacteria we found in 198 samples proved to be resistant to
antibiotics commonly used to treat people. The frequent use of low-dose
antibiotics in pork farming may be accelerating the growth of drug-resistant
"superbugs" that threaten human health.
